With Deryck Whibley As Avril Lavigne, Celebrity Halloween Costumes Were Really Meta This Year

Looking through photos from the hottest Halloween parties over the weekend, it’s clear that all of these celebrities’ stylists told them that meta is in. The more self-referential, the better! The one that takes the cake is Sum 41 frontman Deryck Whibley, also known as Avril Lavigne‘s ex-husband: He dressed up as his surly ex, while his girlfriend donned some crazy-curly hair to be her new fiancé Chad Kroeger.

Of course, what made it even more amazing was Nickelback‘s response: Hey Deryck loved the costumes! we were going to dress up as you guys this year but all the parties had celebrity themes haha! -CK

Famous people trolling each other… What a beautiful thing. Check out our gallery of celebrity Halloween costumes for more meta looks, some obvious ones, and one or two head-scratchers.

Deryck is unattractive as a man and hideous as a woman. Are you sure Ari Cooper isn’t a man?? They tried so hard to be funny but failed miserably. Chad’s response made the ‘joke’ absolutely priceless LOLOL!!
